Jonathan Hogg 30422ca7c2 esp32/esp32_rmt: Fix RMT looping in newer IDF versions.
When looping, now disable the TX interrupt after calling rmt_write_items()
function to handle change in IDF behaviour (since v4.1).  Also check length
of pulses to ensure it fits hardware limit.

Fixes issue #7403.

Damien George c13853f4da javascript: Rework Makefile and GC so it works with latest Emscripten.
The GC now works correctly using asyncify and the functions
emscripten_scan_stack() and emscripten_scan_registers().  Stack/call depth
is monitored via the use of the pystack option.

Fixes issue #6738.

Krzysztof Adamski feb7e2e864 rp2/machine_rtc: In RTC.datetime, compute weekday automatically.
Calculating the weekday each time you want to set a date is error prone and
tiresome.  MicroPython can do it on its own - hardware on some ports do not
support storing weekday in hardware and always computes it on the fly,
ignoring the value given to the constructor.

During discussion for #7432 the conclusion was that there seems to be no
obvious reason to let user set the weekday to an incorrect value so it
makes sense to just ignore the provided weekday value and always compute
the correct value.  This patch introduces this change for the rp2 port.

Krzysztof Adamski 35b1359a3a rp2: Use 0=Monday datetime convention in RTC.
The RTC in rp2 can store any, even wrong, number as a weekday in RTC.  It
was, however, discussed in #7394 that we would like to unify all ports and
use 0 as Monday, not Sunday in the machine.RTC implementation.

This patch makes sure that the default date set in RTC is adheres to this
convention.  It also fixes the example in quickref to use proper weekday to
avoid confusion.

Amir Gonnen cb332ddae8 unix/modffi: Add option to lock GC in callback, and cfun access.
Add an optional 'lock' kwarg to callback that locks GC and scheduler.  This
allows the callback to be invoked asynchronously in 'interrupt context',
for example as a signal handler.

Also add the 'cfun' member function to callback, that allows retrieving the
C callback function address.  This is needed when the callback should be
set to a struct field.

The implementation uses the LPUARTx devices.  Up to 8 UARTs can be used,

For Tennsy 4.0 and 4.1 the UART numbers are as printed on the pinout 1..N.
The MIMXRT10xx-EVK boards have only one UART named, which gets the number
1.  All other UART are assigned to different Pins:

MIMXRT1010-EVK:
    D0/D1   UART 1

This change moves the datetime tuple format back to the one used by all the

Weekday is a number between 0 and 6, with 0 assigned to Monday.  It has to
be provided when setting the RTC with datetime(), but will be ignored on
entry and calculated when needed.

The weekday() method was removed, since that is now again a part of the
datetime tuple.

The now() method was updated so it continues to return a tuple that matches
CPython's datetime module.

Krzysztof Adamski 37d01d4be3 rp2/machine_rtc: Add initial support for RTC.
Initial support for machine.RTC on rp2 port. It only supports datetime()
method and nothing else. The method gets/returns a tuple of 8 items, just
like esp32 port, for example, but the usec parameter is ignored as the RP2
RTC only works up to seconds precision.

The Pico RTC isn't very useful as the time is lost during reset and there
seems to be no way to easily power up just the RTC clock with a low current
voltage, but still there seems to be use-cases for that, see issues #6831,
and a Thonny issue #1592. It was also requested for inclusion on v1.15
roadmap on #6832.

This commit adds full support for a filesystem on all boards, with a block
device object mimxrt.Flash() and uos.VfsLfs2 enabled.

Main changes are:
- Refactoring of linker scripts to accomodate reserved area for VFS.  VFS
  will take up most of the available flash. 1M is reserved for code.  9K is
  reserved for flash configuration, interrupts, etc.
- Addition of _boot.py with filesystem init code, called from main.c.
- Definition of the mimxrt module with a Flash class in modmimxrt.[ch].
- Implementation of a flash driver class in mimxrt_flash.c.  All flashing
  related functions are stored in ITCM RAM.
- Addition of the uos module with filesystem functions.
- Implementation of uos.urandom() for the sake of completeness of the uos
  module.

It uses sample code from CircuitPython supplied under MIT license, which
uses the NXP SDK example code.

Done in collaboration with Philipp Ebensberger aka @alphaFred who
contributed the essential part to enable writing to flash while code is
executing, among other things.

Philipp Ebensberger ff5d39529c mimxrt: Implement machine.Pin class.
- modified pin type from pin_obj_t to machine_pin_obj_t
- created machine_pin.c
- implemented basic version of make-pins.py to genertate pins.c/.h files
  automatically; the only alternate function currently supported is GPIO
- added af.csv files for all supported MCUs
- replaced pins.c/pins.h files with pin.csv for all boards
- implemented on/off/high/low/value/init methods
- Implemented IN/OUT/OPEN_DRAIN modes
- modified LDFLAGS for DEBUG build to get usefull .elf file for debugging

Damien George ea81bcf1c0 stm32/mboot: Leave bootloader from thread mode, not from IRQ.
Leaving the bootloader from an IRQ (eg USB or I2C IRQ) will not work if
MBOOT_LEAVE_BOOTLOADER_VIA_RESET is disabled, ie if mboot jumps directly to
the application.  This is because the CPU will still be in IRQ state when
the application starts and IRQs of lower priority will be blocked.

Fix this by setting a flag when the bootloader should finish, and exit the
bootloader always from the main (top level) thread.

This also improves the USB behaviour of mboot: it no longer abruptly
disconnects when the manifest command is sent.

Damien George 748339b281 stm32/uart: Configure pull-up only on RX and CTS, not TX and RTS.
RX and CTS are the input pins and pull-ups are enabled so they don't cause
a problem if left unconnected.  But the output pins don't need a pull up
(they were originally all configured with pull up in commit
8f7491a109).

If needed, the pull-ups can be disabled in Python using machine.Pin after
the UART is constructed.

See issue #4369.

Damien George a96afae90f stm32/sdio: Fix case of SDIO DMA turning off mid transfer.
The DMA driver will turn off DMA if it hasn't been used for an amount of
time (to save power).  The SDIO driver for cyw43 WLAN was not informing the
DMA driver that it was using DMA and there was a chance that the DMA would
turn off in the middle of an SDIO DMA transfer.  The symptoms of this would
be printing of SDIO error messages and a failure to communicate with the
cyw43 WLAN module.

This commit fixes this issue by changing the SDIO driver to use the
dma_nohal_XXX API to initialise and start the DMA.

Damien George 9a0bca2c2a stm32/mboot: Make LEDs and reset-mode selection more configurable.
A board can now customise mboot with:
- MBOOT_LED1, MBOOT_LED2, MBOOT_LED3, MBOOT_LED4: if it needs to have
  different LEDs for mboot compared to the application
- MBOOT_BOARD_LED_INIT: if it needs a fully customised LED init function
- MBOOT_BOARD_LED_STATE: if it needs a fully customised LED state-setting
  function
- MBOOT_BOARD_GET_RESET_MODE: if it needs a fully customised function to
  get the reset mode

With full customisation, the only requirement is a single LED to show the
status of the bootloader (idle, erasing, flashing, etc), which can be
configured to do nothing if needed.

Damien George 6639e282c7 stm32/mboot: Add MBOOT_LEAVE_BOOTLOADER_VIA_RESET option.
It is enabled by default to get the standard behaviour of doing a reset
after it is finished, but can be disabled by a board to jump straight to
the application (likely the board needs to use MBOOT_BOARD_CLEANUP to make
this work).

The application is passed a reset mode of BOARDCTRL_RESET_MODE_BOOTLOADER
if the bootloader was active and entered via a jump.

This new logic is equivalent to the old logic when the only possibilities

case.  But the new logic also allows other reset_mode values (eg
BOOTLOADER) to run boot.py and main.py.
